I want to have a panel (User Interface) with 3-4 different cropping image options and the user shall be able to chose the size he likes.
For instance, I could have subplot(2,2,1-4) four different cropping window sizes, of an image.
For example, a big cropping area of the image, a smaller one by 30%, an even smaller one by 50% of the original image, and a finally a very thin and slight strip of image.
By mouse clicking, the user can chose the appropriate cropping image window size for further processing.
Is it possible to do that?
